At school:
25 * 15 = 375
The student would only be able to write 375 words for the 1,000 word essay in 15 minutes since the student writes 25 words per minute. Meaning that there would be only be 625 words left to write.
At home:
625 / 25 = 25
25 * 25 = 625
625 + 375 = 1000
It will take the student 25 minutes to write 25 words per minute for 625 words left for a 1,000 word essay at home after writing 375 words at school for 15 minutes.
Hope this helps!
